Fuel is made up of 2,2,4-trimethylpentane (iso-octane). Use bond dissociation energies to determine how much energy can be generated per mole of iso-octane.
If 28.9 grams of trans-2-butene reacts with 14.2 grams of HCl to form 15.5 grams of chlorobutane, what is the percent yield?
What is the pH of the final solution? Answer IS 7.58 Q 3.) What additional volume of 10.0 M HCl would be needed to exhaust the remaining capacity of the buffer after the reaction described in Part B?
Type your question hereA 0.1390-g rock sample of unknown concentration was dissolved in HCl and diluted to 100.0 mL. Aliquots of 10.00 mL of this unknown solution were added to different volumes of a 2.08 ?g/mL Ca standard solution and diluted to ..
Write the expression for the reaction rate in terms of d[NOCl]. c. The concentration of NOCl drops from 0.580 M to 0.238 M in 8.00 min. Calculate the average rate of reaction over this time interval.
According to molecular orbital theory which of hte following is not predicted to exist I know its He2 but how do you get bond order from that is there an easy way
A gas mixture is made by combining 8.1 g each of Ar, Ne, and an unknown diatomic gas. At STP, the mixture occupies a volume of 19.20 L. What is the molar mass of the unknown gas?
A water sample was taken from a lake. A 100.00mL portion of this sample was pipetted into a 250mL Erlenmeyer flask. EriochromeBlack T-indicator, sodium cyanide, and ammonia buffer
Suppose a volume is divided into three equal parts. How many microstates exist for distributing four molecules among the three parts?
draw 1-fluoropentane and predict the number of hydrogens per signal in a H-NMR spectra, and the splitting for each signal?
A solution is made by mixing 8.00 (millimoles) of and 1.00 of the strong base. What is the resulting pH?
A common way of removing Cr3+ from solution is by precipitation of Cr(OH)3(s). An environmental engineer tells you that adjusting the pH to 8.5 will decrease total soluble Cr(III) to below 1 mg/L (1.92 x 10-5 M). Is this true?
